Projects in Phononics

Phononic materials are a sub-class of metamaterials that can manipulate elastic waves and vibrations in solids. Our studies cover a broad range of phononic structures, starting from simple mass-spring networks to complex three-dimensional architectures with target functionalities at broadband sound and ultrasound frequencies.


Dissipative polymer phononics

The dynamics of a phononic medium is governed by its geometric architecture rather than the chemical composition of constituent materials. We show that viscoelastic material behavior affects wave dynamics and provide guidelines on how to predict wave behavior in thermoplastic and thermoset phononic plates.

Broadband attenuation and waveguding in phononics

This project aims at the design of phononic structures capable of attenuating elastic waves at broadband frequencies, including the challenging low-frequency range. The wave attenuation functionality also allows achieving waveguiding along an arbitrarily shaped wave path with a strong wave localization.
